Gatland is heading back to New Zealand

Gatland has asked to be released from the final year of his contract, after going through with his desire to return home to New Zealand in the summer.

Wasps say they are likely to grant the request at a 22 February board meeting.

"Warren has informed us of his wish to leave the club," confirmed club chairman Chris Wright. "The board is likely not to stand in his way."

Gatland joined Wasps from Ireland as forwards coach in January 2002 and was appointed director of rugby two months later after Nigel Melville's departure to Gloucester.

In the following season, Gatland led Wasps to Parker Pen Challenge Cup glory as well as the Zurich Premiership title.

Wasps then followed up that success with the memorable Heineken Cup and Premiership double last year.

But Gatland hinted last June that he may want to leave the club early and return to New Zealand - a decision that he has now confirmed.

"I've decided to move on at the end of this season and go back to New Zealand with my family after spending nine great years away from home," he added.

"I've not got another job despite the various press rumours.

"I've had a fantastic time at Wasps but there comes a time when one has to choose between job and family, and for once I've decided to put my family first."

Wasps skipper Lawrence Dallaglio paid tribute to Gatland and said he would be sorry to see him go.

It's a daunting task but there are plenty of people who will want to do it Wasps chief executive David Davies on Gatland's successor

"Historically, London Wasps have always produced good results but since Warren took charge those good results have turned into silverware," he said.

"On behalf of the players, it's been a privilege and pleasure to work under him and behalf of all players we wish him well."

Wasps Chief Executive David Davies told BBC London 94.9 the search for Gatland's successor would not be easy.

" How do you follow someone as successful as Warren? It's the same problem as the bloke who follows Alex Ferguson. It's a daunting task but there are plenty of people who will want to do it.

"Our dressing room has a number of experienced players who've won World Cups and hundreds of caps. Whoever comes in has to look them in the eye and command respect, and there aren't many who can do it."
